- fix Get_Size_Via_statfs() handling of /data/media storage (/sdcard and /storage/sdcard0 aren't recovery.fstab entries in this case)
- ors backup target: ensure user doesn't enter a non valid volume mount point in recovery settings file
- format_device() could fail to wipe /sdcard on /data/media devices (actually called only by nandroid_restore_partition_extended() to restore /data/media)
- format_volume() could fail to wipe /sdcard on /data/media devices (edify scripting)
- ensure_path_unmounted() could not unmount /sdcard path on /data/media devices
- do not show partition sdcard menu for voldmanaged devices unless they have a valid blk_device2
- use blk_device2 to partition sdcard and to format in ext2/ext3 for voldmanaged volumes
- allow custom format of voldmanaged volumes if fs_type == auto even if they cannot be partitioned (!can_partition)
